iPhone Crash Log doesn't contain methods or line numbers
my app crashed, then I connected my iPhone to my Mac OS X, found the crash log in the "Device Log"-section of XCode.
What do I have to do to see methods or line numbers? I don't know where to look for the error with the information provided... Thanks a lot!

You need to symbolcate the crash log. That will tell you where in your custom code the crash happened.
If you are developing this app then try debugging it in the simulator. I've found it produces more complete crash reports (dumped to the Apple console) than symbolicated device logs. Good luck!
Steps to analyze crash report from apple:
Copy the release .app file which was pushed to the appstore, the .dSYM file that was created at the time of release and the crash report receive from APPLE into a FOLDER.
OPEN terminal application and go to the folder created above (using CD command)
atos -arch armv7 -o ''/'<.dSYM filename here>' . The memory location should be the one at which the app crashed as per the report.
Ex : atos -arch armv7 -o 'AHLAN! HOT100.app'/'AHLAN! HOT100' 0x0003b508
This would show you the exact line, method name which resulted in crash.
Thanks
